Pretty good. Looks like you are walking pretty straight and your arm swing is pretty smooth. My only suggestion would be to slow down. You are on the verge of running up to the line. Your foot speed adds almost nothing to your ball speed and if you slow down you are more likely to get a more repeatable swing. I know every time I start having trouble getting the ball into a good swing plane it is because my feet are getting fast. Watch the pros, pretty much all of them are in no hurry to get to the line and it allows their body to set up better and requires less muscle.
Always be sincere, even when you don't mean it
